Exercise-Induced Changes in Knee Cartilage In Vivo: Comparing MRI Sequences.
Article in Journal of orthopaedic research : official publication of the Orthopaedic Research Society, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The purpose was to assess the agreement in measures of acute knee cartilage thickness and composition change after loading in clinical knee osteoarthritis (OA) between two magnetic resonance imaging (MRI) acquisition approaches: (1) single sequence approach using quantitative double-echo in steady-state (qDESS), which allows simultaneous morphological and compositional scanning, versus (2) multi-sequence approach that captures morphology (fast spoiled gradient recalled (FSPGR) or qDESS) and composition (multi-echo spin echo (MESE)) separately. Twenty adults with clinical knee OA participated. 3T MR scans were acquired before and immediately after a 25-min treadmill walk at a standardized speed. Changes in knee cartilage thickness and T2 were assessed. Pre-activity, strong agreement was observed in cartilage thickness captured with qDESS and FSPGR (concordant correlation coefficients 0.842-0.935). Pre-activity, we observed greater absolute cartilage thickness with qDESS compared to FSPGR in femoral cartilage. From pre- to post-activity, qDESS showed change in cartilage thickness in the medial femur (-0.088 ± 0.11 mm, p = 0.002), lateral tibia (-0.042 ± 0.65 mm, p = 0.011) and trochlea (-0.027 ± 0.05 mm, p = 0.024); whereas FSPGR showed a change only in the lateral tibia (-0.064 ± 0.08 mm, p = 0.002). From pre- to post-activity, qDESS showed reduced T2 in all cartilage regions; whereas qDESS + MESE and FSPGR + MESE detected T2 changes in the patella (-1.90 ± 3.00 ms, p = 0.013, and -1.80 ± 2.18 ms, p = 0.002, respectively). qDESS detects transient changes in knee cartilage due to loading in clinical knee OA.
